title: N-tert-But-oxy-carbonyl-α-(2-fluoro-benzyl)-l-proline.
abstract: In the title compound, C17H22FNO4, the pyrrolidine ring adopts an envelope conformation with the disordered com-ponents of the methylene C atom, with site occupancies of 0.896 (7) and 0.104 (7), being the flap on either side of the mean plane involving the other atoms of the ring. The carb-oxy-lic acid group forms dihedral angles of 72.06 (11) and 45.44 (5)° with the N-tert-but-oxy-carbonyl group and the 2-fluoro-benzyl group, respectively. In the crystal, two-dimensional layers of mol-ecules parallel to (001) are built through an R 4 (4)(23) motif generated via O-H⋯O, C-H⋯O and C-H⋯F inter-actions, and an R 2 (2)(11) motif generated by C-H⋯O and C-H⋯F inter-actions.
